Geographic Information System (GIS) is a powerful tool for capturing, storing, editing, updating, retrieving, analyzing, modeling, and displaying data that are spatially referenced to the earth.


GIS is made up of the following components: computer hardware, GIS software, databases, procedures and, most importantly, skilled personnel.

GIS Components

GIS integrates data from various different sources and helps to visualize patterns and trends that spreadsheets alone won't portray. GIS allows us to see patterns, linkages and trends that put the big picture in context. GIS allows us to manage places such as watersheds, neighborhoods, communities, and ecosystems.
